Comparing influencers side by side can provide a clear and concise way to view their metrics and performance. Various platforms have features that support this kind of comparison.

1. Upfluence: This platform allows for side-by-side influencer comparisons based on various key metrics such as audience demographics, engagement rates, and estimated reach.

2. Influencity: A similar capability is offered by Influencity, where users can compare selected influencers on the basis of followers, interaction rates, audience interests, and other important metrics.

3. Flinque: Flinque, on the other hand, focuses on providing a more personalized influencer discovery experience. It breaks down influencer audiences into micro-segments for better targeting, helping brands make informed decisions.

4. HYPR: Another platform, HYPR, provides influencer comparison based on advanced analytics such as audience demographics, engagement rates and brand affinities.

These tools all aim to provide marketers with comprehensive influencer evaluation and comparison methods. The most suitable platform for you will depend largely on your specific needs and the particular features that align with them. For instance, if detailed audience segmentation is a priority, Flinque might be a fitting choice. Meanwhile, general performance comparisons may be well-served by platforms like Upfluence, Influencity, or HYPR.
